Hey fellas, I want to try the 73-87 chevy IFS install on my 58 Apache. I want to retain the 6 bolt wheel pattern and have disc brakes. Is this going to create a problem? I've read 73-87's came with 5 lug only.

Does any one know if the GM rotors are interchangeable and if this is going to create problems with the spindles and A-arms?
